Application'ledlhecember1'?, 1912. Serial No. 78'7,92.

To all rar/0m "it may concern: Be it known that l, VICTOR H. SLIriACK, a citizen ot the' United States, and ares'ident ot Philadelphia, in the county of Philadelate of Pennsylvania, have nr vented a certain 'new .and useful hutomatio Gas-Distributer, of which the 'ftollowing is a specification. 1 V

The principal object of the presentimenprovide a `compact, reliable, and eilicient delce which, shall res ond to changes of pressure oli the" as whiehit reoeives and operate to distri ute ,ligas 'to one outlet or burner connection when low pressure is sustained and to another outlet or burner connection when high pressure is sustained,

The invention will he Claimed 'at the en d hereof, 'but will be first described in conneotion with the embodiment of it selected from many other embodiments for illustration in the accompanying drawings, 1n Whioh- Figure l, is-a central sectional View of the distrihuter. Fig. 2, isa front view With parts broken away, and Fig. 3, is a sectional View taken on the line 3'3 of Fig. llook-v ing downward.

l'n the drawings there is a housing shown as made in two parts l and 2. Within this housing there is a closed distribution chamber 3.

l, is an impervious diaphragm shown as clamped between the parts l and 2 and it Vserves to subdivide the distribution chainher. The diaphragmcari-ies a fitting 5, shown as made in two parts, and through this Afitting there is a duet 6 having an opening on each side of the diaphragm. At one end the fitting is provided with a Valve 7 and at the other end with a valve-seat 8. The 'valve 7 has a guiding projection which works in an oil-take 9 that may extend, for eiziniple, to the main burner of a light. The adjustable plug' l0, shown` as having screw and thread Connection through an vopening' in the housing is provided With a valve ll that cooperates with the seat 8 and is provided with a guiding extension that works in the duct (i.

l2, is a spring tending to shift the diaphragm toward the lett in Fig. l.

i3, is a gas ott-take for example tothe pilot burner of a -snre is changed iioin low le, is a gas inlet connectioiii communicatf ing with the distribution chamber side of the diaphragm. It -is4 oeive a supply ofl gas at susY at sustained low pressure, a single line of pipe 'in which 'the Y 'ssi'ire inay he low in the daytine and igh at night.

l5 is a v'alveiii the inlet connection which can be operated by means of the lever 16 and the purpose of this Valve is to shut ott' the supply of gas in oase of emergency or the like. l

The inodegol operation of the descrihed automatic pressure responsive gas distrihter may he explained as follows :-When the pressure of the gas supplied to the inlet 14 on one adapted 4to re- Vaimed higher for exa'ir'iple, troni Patented Mar.. if?, digital. 'y

is maintained low, the spring ll shifts the diaphragm toward the left in Fig. l thus the valve 7 cuts off the gas supply to the outlet -9 and there is an 'opening between the valve l1 and its seat 8 -so that gas passes through the duct 6 and reaches the part of the charnber to the right of the diaphragm and thence passes by the outlet 13 to, for example, the pilot light.4 This is the condition of a'airs corresponding, for example, to daytime. When the gas supplied to the inlet 14 is sutained at high pressure, such pressure overcomes the spring l2, shifts the diaphragm toward the right and holds it in. that positioii; thus the valve 7 uncovers its seat and the seat 8 covers thc-Valve 1l., more or less. Thus the supply of gas at high pressure is 'ted to the outlet connection 9, hut not to the outlet'eonnection 13 or in 'very small quantity. If the outlet connection 9 be connect ed to the main burner of a light this Would be, the condition of alairs corresponding to night. tiine. It is evident that when the presl to high the pilot lights light the inain burners and when the pressure is changed from high to low the main burners light the pilotl li lits, ifeX- tinguished. The. movement o the diaphragni and the opening and closing of the respective valves is properly timed or made suiiioiently slow to accomplish this result. ln other words they diaphragm comparatively slowly responsive to a change oi' pres- Vsure which is sustained.
